This paper introduces and discusses the multi-jackbolt tensioner (MJT) type expansion bolt with split expanding sleeve as a replacement to standard fitted or interference fit bolts that are widely used within industry, including navy and marine environments. For marine uses, applications include shaft and propulsion coupling bolting as well as on anchoring and positioning bolting often required for most line shaft bearings, thrust bearings, and steering gears. Both a Finite Element Method (FEM) study and a shear test were recently performed to confirm superior load carrying ability as compared to standard fitted bolts. Further, results of these tests, installation / removal time comparisons, and calculated costs savings are presented here for consideration.
